Characteristic species

Macrozoobenthos

Mapping
advise (habitat delineation, identification, similar types)

The
area deeper than Secchi depth multiplied by 2.5. Due to temporal variation of
water turbidity, the depth should represent a long-term growth season average. The
absence of foliose vegetation can also be used with other indicators.

Quality descriptors

High
abundance and diversity (“high” is dependent on Sea area) of macrozoobenthos
indicates good environmental status.
